Length under plate of open end parts: values obtained after setting.
To obtain the length under the plate after setting of closed end parts, you can add the following sizes to the above-mentioned:
| Steel and aluminium (mm) | Stainless steel (mm) | ||
| M3 | 3,5 | M4 | 4,5 |
| M4 | 4,5 | M5 | 6,0 |
| M5 | 6,0 | M6 | 7,0 |
| M6 | 7,0 | M8 | 8,0 |
| M8 | 8,0 | M10 | 7,0 |
| M10 | 10,0 | M12 | 10,0 |
| M12 | 10,0 | ||
In some cases the real length will be shorter. All dimensions can be checked on the technical data sheets in our catalogue.
In practice, variations may result from differing setting and environmental conditions. The values mentioned can be used as a reference and optimised by using additional features. We strongly advise customers to perform their own tests in the correct material thickness and specific application.

Setting Force or Upset Load: Force (in Newton) necessary to deform the Tubtara® referred to in an adequate way.
Upset Stroke: Stroke (in mm) that should be set on the setting tool to give the Tubtara® referred to, the adequate deformation.
The mentioned values are average reference values only.
We strongly advise the customer to do his own tests in the proper material thickness and specific application.
Semi-hex parts have a setting force which is 10 to 15% lower than full hex or round parts but have the same fixation strength.
Check the installation tool’s max. setting capacity, especially for M10 and M12.
High Strength Materials
- 23MnB4: +20% higher mechanical strength compared to C8C
- AlMg3,5: +20% higher mechanical strength compared to AlMg2,5
